Not to put too fine a point on it, but this isn't the old days.
Because the flight surfaces do not have force feedback to the PFCs in the Airbus design, trimming the aircraft by feel is not possible in the same way as older designs. This is the main reason why autotrim was developed.
Clandestino pointed out a while back that it can be done visually, but I suspect that you wouldn't want to be doing it all the time.
